, capacity of the suction tubes will be substantially equal to the capacity of tlrgsuction FRANK M. DANNELLY, or DALLAS', TEXAS.

' correu-PICKER.'

Speciation of Letters Patent.

Application led Ianuary 1?, 1 909. Serial No. 472,089.

To a-ZZ whom it 'may concern:

a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented new and useful Improvements in Cotton-Pickers, of which the' following is a specification.

My present invention relates to improvements in cotton pickers or harvesters and more especially to the class wherein the cotton is removed from theboll by suction, and it has for its object primarily to provide an V improved hood for cotton pickers ofthe type shown in Letters Patent, No. 685111 granted to me October 22, 1901, the hood according to my present invention being shaped to straddle a row offcotton lants and is elon, gated to form a longitudinal suction chamber the inner Wall of which is provided with numerous inwardly extending suetiontubes which are arranged in staggered relation longitudinally of the hood and are of different lengths' whereby every portion of the plant will be reached by suchtubes and the ripe cotton will beremoved therefrom without injury to the plant.

Another object of the invention is to pro' vide an improved cotton picker of this character wherein the ca acity of the suction chamber of the hoo and the aggregate pipe through which the cotton is conducted to an appropriate collecting receptacle whereby the velocity of the air through such parts will insure the passage of the removed cotton therethrough.

A further objectief the invention is to provide an improved suction tube toast upon the cotton and remove it from' the its inner reduced end ia'ving inwardly pijpjecting teeth arranged in a plane'at "right angles to' the axis of the tube which teeth permit the entrance of the cotton int o tlie` tube but prevent entrance o f thgboll orbur",n although should such boll iibur enter the tube the increasingy diameter thereof would prevent clogging.

To these and other ends, the ,invention consists in certain improvements, and combinations and arrangements of parts all as will be hereinafter more fully describemfthe novel features being pointed out particularly in the claims at the end of the specification.

-is a side elevation partly in section of a cotton picker constructed in accordance with my present invention; Fie. 2 is an end elevation partly in section et? the cotton picker as shown 1n Fig. l; Fig. 3 represents a longitudinal section-of one of the suction tubes A scribed in my prior patent. No. 685111 granted tome October Q2, 190,1. it will be understood, however, that the invention is notlimited to the precise construction and arrangement of tlieparts as shown in the drawing, as such modifications and changes may be made as may be desirable in applying the invention to ditierent uses.

In the present instance, the apparatus consists ofa hood 1 which is preferably yoke-shape, this hood having an outerwall 2 and an inner Wall 3, these walls'being spaced apart to form a suction chamber li.A The Walls of the hood preferably approach one another toward the lower ends of the hood so that the upper or intermediate portion of the suction chamber will be larger or of greater capacity than its lower portions, and the-upper portion of the outer wall 2 .is

Yprovided with an outlet to which a suction pipey 5 is connected, this suction pipe being attached directly to the hood in the present instance through the medium of a flanged collar 6.

The inner wall 3 of the suction chamber forms a space within it sutlicient to accommodate a row of cotton plants, it being understood that the device straddles the plants and -is moved longitudinally of the row in any suitable manner such', for instance, as by attaching the apparatus to the forward end of a wagon tongue 7. Projecting in wnrdiy from the wall 3 are the suction tubes 8 which are arranged in rows extending longitudinally of the suction chamber, the tubes in the several longitudinal rows being staggered so that the. tubesiwill reach everytio portion of the plant. Certain of the, tubes in the accompanyingdrawing: Figure l are also longer than others ser that such tubes will be able to reach inwardly toward the center of the plant and thereby remove 'cotton which is not exposed at the exterior ofthe plant. The size and number vof suction tubes Lis `preferably such that their aggregat capacity is preferably equal to the capacity of the suction chamber 4, and in turn the capacity of this suction. chamber is preferably equal to thecapacity of the suction pipe through these parta-.will be 'substantially with a flange 9 and providing'the smaller end of the tube wedging or c and, moreover,

tubesso operate in by the suction and theteeth -engage thecotton and thereby hvold it within Athe mouth Y of the tube while the chamber is moving,

of thesuction can -'remove all of the cotton from the boll, these with teeth as shown, the ripevcotton will be permitted. to enter the tube while the teeth will engage the cotton; they serve to reduce the entrance of the tube to a diameter smaller than the boll or bur and thereby'preventv such boll or bur from entering the tubeorY becoming caught in the end of the tube in such a manner. as would clog it. However, should `a boll enter the, tube by. any possibility,l it could not clog the tube fior the 'reason that'the' tube is ofgreater diameter than the space formed between the.teeth the tubeA would `prevent such bodies fromv logging the tube.

to fthe present invention, the

According l that the lint will .be drawnalong the row of plants, until the full action take effect and thereby teeth 'also serving to reduce the area of the tube although-theydo not obstruct` the entrance of the cotton.I It will be understood, of course, that by decreasing .the number of tubes, 'the velocity of the air current can be increased to any desired speed at the mouth Aor small end of the suction tubes :for the purpose of increasing the suction power at that particular point, or the diameter4 at the mouth of the tubes can be decreased'to pro duce the same result. ,i The suction chamber, it. will .be understood, is elongated or of a' considerable length, and throughout its .length extend 4rows of suction-tubes which are arranged in approximately radial relation to'l a central 5 so that the draft or suctionv form, it being tapered or other-means by which itlane substantially' the increasing diameter of v zone whereintheplant is located.. Such an arrangement insures4 that every portion` of suction tube and hence al1 ripe cotton will be removed from the plant.

I' claim as my invention:

l. A cottonpicker comprising a-suction chamber having portions which extend laterally and )are arranged to pass upon opposite their outer ends with the chamber and ar-` ranged substantially radially so as to converge toward a central suction zone.

2. A cotton picker comprising a suction chamber inthe form of a hood embodying a pair1 of laterally spaced opposed sections adapted to straddle a row-@plantsand connected by said hood to a common outlet`,said chamber being elongated in the direction of its length., suction tubesprojectinv inwardly -from the "opposed sections ofl t e. suction chamber and converging toward a central suction zone which has an axis arranged longitudinally of the suction chamber, said tubes being arranged in horizontal rows with those in one row staggered with respect to those in adjacent rows.

3. A cotton picker comprising a suction chamber havinof its opening lownward, and a lurality of suction tubes projecting inward y' from the suction chamber and converging toward a central suction zone which hasan axis parallel to the length of the cotton picker.

- .A cotton icker comprising a relatively 6. A cotton picker com rising a relatively;
